The Chorea remains mysterious – it sometimes seems to appear without reason, while it is known that a certain lovely white flower sometimes found deep in forests will trigger it if its pollen is inhaled by a human. Perhaps the pollen drifts in the wind, or perhaps fey spirits like playing tricks with it from time to time. Whatever the case, it manifests with rapidly emerging exaggerated sociability, a lack of caution, and the gradual development of a sort of jovial irrationality among the infected.

What is sometimes mistaken as mere lapses in judgement and partying, the disease becomes markedly identifiable once the convulsions and “dancing” begin: a wild jerking, and later animalistic stomping about, entirely uncontrollable by the sickened and followed by brutish violence if any bystanders endeavor to put a stop to it. Eventually, the sick begin to lose themselves, seeking only to continue their “dancing”, happy to use any sort of intoxicants available to fuel their euphoria. If left untended, those so afflicted will die of exhaustion, the side effects of whatever they are consuming, or from unintended self harm in their wrathful frivolity. Humans exposed to the flower must pass a DC 10 Constitution save or be infected.

On success, they instead feel a short-lived euphoria with no lasting ill effects. Sometimes this is enough to prompt repeated exposure. Those so infected find themselves behaving as above, and are entirely unable to rest after a week, involuntary “dancing” essentially non-stop and crave any mindaltering substance they become aware of nearby.

Long Rests become impossible for the duration, and they must pass a DC 13 Constitution save or take 1 exhaustion each day, in addition to any incurred through a loss of sleep.

The disease always lasts precisely 1 week after infection.
